How-to Force Cached Credentials to Update

We've had issues with cached credentials not updating when a user’s password expires while he or she is away from the office. The only connection into the network is through terminal services (non-VPN) and the password is changed on the terminal server.  The problem is that the cached credentials on the user’s laptop are not updated, even after the user connects via VPN for a while.  Here is the easiest way I've found to force cached credentials to update to the new password.  While connected via VPN, have the user lock their laptop (Win+L) and then unlock the laptop using the new password. This procedure forces the laptop to check in with the domain controller and authenticate using the new password.
